Right... because it's perfectly acceptable and professional to refuse to play for your team in any circumstance.
Like to see how you would react if he did that for Juventus, if he's gonna do it once he can do it again. If you told your boss at work you didn't feel like working you would be out the door like that, regardless what you think of Man City and Mancini that is disgusting behaviour by Tevez.
And I'm not embarrassing myself because I'd be happy to debate with you or anyone why I think that Tevez isn't a massive upgrade on Vucinic, and given that the majority of posters here are from the USA, Australia, Eastern Europe, Middle East etc. I'd be willing to bet that I've probably seen more live matches and on a regular basis then most people here and given my background in sports journalism I think I'm pretty qualified to make that point.
